Note: this shows relative popularity of *new* apps using *clickstarts* to get started - and thus is an interesting leading indicator of what people are trying out/starting with.
The good old trusty ones are still there: Hibernate/Tomcat, Facebook and Scala/lift (holding strong).
Some interesting changes:
Up: Tomcat7 (new), AngularJS, iOS starter app with CouchDB (new). Google App Engine with Python.
Down: Clojure/compojure (where’s the love!), Hibernate/Tomcat (perhaps Tomcat7 took some of the interest)
I am not crazy enough to predict what the next report will be like - it is muddied by the fact that we are introducing new things into the mix each month (we are working on better ways of presenting the clickstarts to make it clear what each one offers, what the support for it is like, popularity etc).
